This Standard Size Reverse Osmosis Membrane fits in a standard membrane housing.
FILMTEC home drinking water elements are rated at 50 psi and will purify about 20% more water than competitive elements rated at 60 psi (please see the datasheet for more information).
Membrane has one year shelf life. Be sure to use it right after your purchase. You normally need to change membrane every two years.
You get a better wholesale price when order in huge quantities. So you can retail the membranes at a lower price. Towards the end of the year, you might buy the membranes that were brought by these lower price retailers at the very beginning of the year.
